To get Storale running you can simply go download the latest build from ActivePerl (its included by default).

I use a very similar method, cept for extra security I also use the stuff from http://pajhome.org.uk/crypt/index.html to get the user submitted pwd across safely (I don't have SSL).

I use BerkeleyDB for the DB backend && it goes something like this:
$my_cool_db{'some_key'} = freeze({what=>'ever'}); my $var = thaw($my_cool_db{'some_key'});
